Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a cutting device for cutting the stems and roots of bulbs of onions, garlic, chili peppers, etc. at the same time.

Conventional technology In general, bulbs such as onions and garlic are widely used as cooking ingredients, but before shredding them, the stems and roots of the bulbs are cut and the outer skin of the bulbs is peeled off. If you want to process this in large quantities, you will naturally have no choice but to rely on mechanical methods.

However, unlike industrial products, scales are irregular in size and shape, so if the cutting device is configured to cut the stem and root of the scale by setting the cutting blade in a fixed position, When cutting the top and bottom of the bulb and removing the stem and root at both ends with just one machine input, depending on the size and shape of the bulb, the cutting allowance for the stem may be too much and the effective part may be lost. There may be a shortage, requiring recutting by machine or hand.

In particular, if the stems of the bulbs have not been cut enough to be sorted out from among the bulbs after cutting, there is a risk that the effect of mechanizing the cutting work will be halved.

Conventionally, a first support body and a second support body are respectively disposed on the aircraft body so as to be movable in the vertical direction, and a first support body and a second support body are provided with a horizontal cut surface facing the first support body and the second support body. A cutting device for cutting the stem and root of a bulb is disclosed in Japanese Patent Application Laid-Open No. 2003-110016. A cutting device for cutting the stem and root of a bulb includes a first cutter and a second cutter that are rotatably provided, and guide pieces that protrude forward from the first support and the second support, respectively. 1986-241
It has been proposed as Publication No. 878.

Problems to be Solved by the Invention However, the device described in JP-A-60-241878 requires a drive device for rotating the first cutter and a drive device for rotating the second cutter, which reduces the overall efficiency of the device. The height has increased.

An object of the present invention is to move the bulb along the longitudinal direction between the derivative of the first support and the derivative of the second support, so that the first support becomes the first support as the bulb moves. The first swinging link moves upward while swinging relative to the fuselage, and at the same time, the second support moves the second swinging link downward while swinging relative to the fuselage as the scale moves. Then, the first cutting blade moves upward together with the first support while keeping the cutting surface in the horizontal direction, and the second cutting blade moves upward together with the second support while keeping the cutting surface in the horizontal direction. moving downward, a single drive unit rotating the first cutting blade and the second cutting blade, and a conventional drive unit rotating the first cutting blade and the second cutting blade; There is no need for a separate drive device to separate the stem and the root, and at the same time the bulb with the stem and root cut passes between the first cutting blade and the second cutting blade, the first cutting blade and the second cutting blade To provide a cutting device for cutting the stem and root of a bulb, in which the height of the entire device is made as small as possible by bringing the bulbs close to each other by a biasing means through a first swing link and a second catching link. There is a particular thing.

Means for Solving the Problems The bulb stem and root cutting device of the present invention has a first swinging link consisting of link rods parallel to each other and a second swinging link consisting of link rods parallel to each other. Swing links are arranged to be swingable in the vertical direction, and a first support body and a second support body are respectively swingably provided at one ends of the first swing link and the second swing link. In addition, a first cutting blade and a second cutting blade, each of which has a horizontal cutting surface, are provided on the first support body and the second support body so as to be rotatable while facing each other, and
a support body and a second support body each having a guide body protruding from the front thereof, and biasing means for forcing the first cutting blade and the second cutting blade to approach each other on the second swing link; , and the machine body is provided with a single drive device for rotating the first cutting blade and the second cutting blade.

Working scales protrude from the front portions of the first support and the second support at one ends of the first swing link and the second swing link, which are respectively disposed on the fuselage so as to be swingable in the vertical direction. When the first support moves in the longitudinal direction between the provided guides, the first support moves upward while swinging the first swing link with respect to the fuselage as the scale moves, and at the same time As the scale moves, the second swing link moves downward while swinging relative to the machine body, and the first cutting blade rotatably provided on the first support cuts the cutting surface. The second cutting blade rotatably provided on the second support moves together with the second support while keeping the cutting surface horizontal. Moving downward, the first cutting blade and the second cutting blade are spaced apart depending on the size and shape of the scale, and a single drive device provided in the machine moves the first cutting blade and the second cutting blade. The blades are rotated, and the stem and root of the bulb are cut by a constant cutting depth with the first cutting blade and the second cutting blade, regardless of their size and shape.

Also, as the bulb whose stem and root have been cut passes between the first cutting blade and the second cutting blade, the biasing means provided on the second swing link is caused to engage with the first cutting blade. and the second cutting edge are brought close to each other.
